Winnipeg police have charged a 20-year-old man who was found to be carrying a noxious substance in his backpack Saturday at the Health Sciences Centre.

Police along with fire crews were called to the hospital at about 7 a.m. CST after security officers reported a man was causing a disturbance.

Officers also closed off a road near the hospital for most of Saturday morning.

Deputy Fire Chief, Bill Clark told CBC a white substance was found when security officials checked the man's backpack.

When they looked in the bag, a noxious odour came from inside.

The substance also caused the eyes of bystanders to sting and water.

The man also had a piece of broken glass in his backpack which officers treated as a potential weapon.

No one was hurt in the incident.

The man is facing charges of mischief endangering life, possession of a weapon for a dangerous purpose and causing a disturbance.
